Observations by NASA's Hubble Space Telescope indicate that the upper atmosphere of the hot Jupiter exoplanet HAT-P-38b is free of clouds or hazes, whereas most of the atmosphere of WASP-67b — a similar planet in many ways — is masked by high-altitude clouds.

NASA's Near-Earth Object Wide-field Infrared Survey Explorer mission has released its third year of survey data, with the spacecraft discovering 97 previously unknown celestial objects in the last year.

A giant gas planet - up to fifty times the mass of Jupiter, encircled by a ring of dust - is likely hurtling around a star more than a thousand light-years away from Earth, according to new research by an international team of astronomers, led by the University of Warwick.

More than 700 volunteer citizen scientists have helped identify more than 30,000 celestial objects, including a star explosion that occurred 970 million years ago, hundreds of millions of years before dinosaurs emerged on Earth.
